Scene of Boston bombing reopens; slain MIT police officer honored

A week and a half after terror ripped through the heart of Boston, a sign of recovery arrived on Boylston Street, where the marathon had come to an abrupt, horrifying end.

"The people of Boston are strong like cement. Strong people. They get together when it's needed," said Robert Dibiase, a city masonry worker who early Wednesday cemented over what had been a blood-stained, debris-filled crime scene. "I'm proud, but in the meantime, I'm sad."

Since last Monday -- when twin bombs exploded near the finish line of the marathon, killing three people and injuring more than 200 -- Boylston Street has been closed. The normally bustling street was rendered eerily quiet -- a constant reminder to the grieving city of what had happened.
